Family CRYPTOLARNACIIDAE Dumitrica, 1989 n. stat.

Cryptolarnaciinae Dumitrica, 1989: 241-242 . — De Wever et al. 2001: 156. — Afanasieva et al. 2005: S287. — Afanasieva & Amon 2006: 130.

TYPE GENUS. — Cryptolarnacium Dumitrica, 1989: 246 [type species by monotypy: Cryptolarnacium hexastylus Dumitrica, 1989: 246 ].

INCLUDED GENERA. — Coccolarnacium Dumitrica, 1989: 242 . — Cryptolarnacium Dumitrica, 1989: 246 . — Globolarnacium Dumitrica, 2020: 13. — Phacolarnacium Dumitrica, 2020: 7. — Pylolarnacium Dumitrica, 2020: 16.

NOMEN DUBIUM. — Staurosphaerantha .

DIAGNOSIS. — The shell of the phorticiid-type structure is completely hidden within a cortical shell, that strikingly resembles the cortical shell of some co-occurring spumellarians. However, in Cryptolarnaciidae this layout is separated by an empty space or a loose spongy framework.

STRATIGRAPHIC OCCURRENCE. — Late Paleocene-Late Eocene.

REMARKS

This group is raised herein from the subfamily Cryptolarnaciinae (originally included in family Larnacillidae ) to the family level in order to maintain rank consistency. Internal skeletal structure for Coccolarnacium ( Dumitrica 1989: pl. 10, figs 1-4; pl. 14, figs 2-4, 9) and Cryptolarnacium ( Dumitrica 1989: pl. 10, figs 5, 6, 10; pl. 14, figs 5, 6) was illustrated. This family member is found in plankton samples from the Pacific Ocean, South China Sea and Eastern Indian Ocean (e.g., Onodera et al. 2011: pl. 4, fig. 13).
